Our work to help water voles
Once a common sight along the banks of Britain's rivers and lakes, water voles are now among our most endangered species. The National Trust is helping to protect them with land management programmes and projects to reintroduce them to the places where they once thrived.
Water voles in danger
Water voles have been in decline for several decades and are now thought to have disappeared from more than 90 per cent of the rivers, streams and lakes where they once lived.
Pollution and the loss of their natural habitats are both major contributors. But many water voles have also fallen prey to an invasive species, the American mink, which established wild populations in Britain in the 1950s after escaping from fur farms.
Why protecting water voles is important
Immortalised by 'Ratty' in children’s classic The Wind in the Willows, water voles are arguably one of Britain's most endearing animals. To see them disappear for good would be a tragedy.
But water voles are also part of complex ecosystems, meaning their presence comes with benefits for other plants and animals.
Water voles are a source of food for struggling predators like barn owls and otters. Where they graze on grasses and rushes, they create space for rare plants to grow. And they can even help reshape entire habitats.
Our work for water vole conservation
Since 2007, our countryside teams have been surveying rivers and lakes for signs of water voles in order to assess population levels and look at what actions to take.
